BACKGROUND OF THE INVENTION

a) Field of the Invention

The invention relates to a sealing plug of a toilet tank and, moreparticularly, to a sealing plug structure for fine-tuning a merged angleautomatically, to thereby being covered on the drain opening withdifferent tilt angle.

b) Description of Prior Art

FIG. 1 is a cross-sectional diagram of a conventional toilet tank levelstructure A, wherein a sealing plug 1 includes a cover 11 and twosupporting arms 12, a notch 13 is set on a rear end of the supportingarms 12, the notch 13 is set on a positioning column 211 of a flush pipe21, the sealing plug 1 is covered on a drain opening 221 of an overflowpipe 22. In is the abovementioned conventional structure, there is aproblem in use, it is mainly because that the tilt angle of the drainopening 221 manufactured by different manufacturer may be a littledifferent. The sealing plug 1 is an integrated soft plug body (as shownin FIG. 2). In the early stages of use, the sealing plug 1 could beapproximately covered on each type of drain opening 221 with the softproperty of its material. But after a period of time, the material ofthe sealing plug 1 hardens and its original soft elastic propertygradually disappears, so that the drain opening 221 cannot be completelycovered and water leakage may easily happen. For this reason, consumersare forced to change the sealing plug 1 periodically. Furthermore,consumers usually find water leakage after it happens for a long periodof time, so that water rate increases and it also wastes water.

To achievethe object, according to the invention, the sealing plug of a toilettank of the present invention, which includes a cover and aninstallation seat, wherein:

the cover, two corresponding shaft columns are set on its top;

the installation seat, two corresponding supporting arms are set on it,two shaft holes are respectively set on a front end of the supporting toarms, the shaft columns are used to inserted into the shaft holes, anotch is set on a rear end of the support arms, the notch is used to seton a positioning column of a flush pipe;

by the composition, the sealing plug is provided for fine-tuning amerged angle automatically, to thereby being covered on the drain isopening with different tilt angle.

The cover includes a holder, a soft plate body and a hemisphericalshell, the holder is set on the top of the cover, a through hole set ona rear end of the holder is provided to connect to an end of a chain,the soft plate body fixedly installed between the holder and thehemispherical shell is provided to cover on a drain opening of a toilettank level structure, the hemispherical shell is installed on a bottomside of the cover.

The supporting arms, an inner lower slot and an outer upper slot arerespectively set on two sides of the front end of each supporting arm,the shaft holes are laterally punched through the inner lower slots andthe outer upper slots.

The supporting arm, a clip groove is set on its rear end, and the notchis set on a lower side of the clip groove to form two slip side arms.

DETAILED DESCRIPTION OF THE INVENTION

Please refer to FIG. 3, FIG. 4 and FIG. 5, the sealing plug 3 of thepresent invention includes a cover 31 and an installation seat 32,wherein:

the cover 31, two corresponding shaft columns 311 are set on its top;

the installation seat 32, two corresponding supporting arms 320 are seton it, shaft holes 321 are respectively set on a front end of thesupporting arms 320, the shaft columns 311 are used to inserted into theshaft holes 321, a notch 324 is set on a rear end of the support arms320, the notch 324 is used to set on a positioning column 411 of a flushpipe 41;

by the composition, the sealing plug 3 is provided for fine-tuning amerged angle θ automatically, to thereby being covered on the drainopening 421 with different tilt angle.

The abovementioned cover 31 includes a holder 312, a soft plate body 310and a hemispherical shell 314, the holder 312 is set on the top of thecover 31, a through hole 313 set on a rear end of the holder 312 isprovided to connect to an end of a chain 315, the soft plate body 310fixedly installed between the holder 312 and the hemispherical shell 314is provided to cover on a drain opening 421 of a toilet tank levelstructure B, the hemispherical shell 314 is installed on a bottom sideof the cover 31.

Please refer to FIG. 5 and FIG. 6, an inner lower slot 322 and an outerupper slot 323 are respectively set on two sides of the front end ofeach supporting arm 320, the shaft holes 321 are laterally punchedthrough the inner lower slots 322 and the outer upper slots 323, so thatthe shaft columns 311 may be inserted into the shaft holes 321 and athicker to clamping and supporting thickness may be provided to preventit from escaping the shaft holes 321. Also, the merged angle θ forautomatically fine tuned between the supporting arms 320 and the cover31, so that the soft plate body 310 of the cover 31 could be completelycovered on the drain opening 421 of the overflow pipe 42.

The supporting arm 320, a clip groove 325 is set on its rear end, thenotch 324 is set on a lower side of the clip groove 325 to form two slipside arms 326, 327 for fixedly clipping the positioning column 411 ofthe flush pipe 41.

By the composition of above structure, when the sealing plug 3 of thepresent invention is installed to cover on each drain opening 421manufactured by different manufacturers, even the tilt angle of eachdrain opening 421 is different, the merged angle θ may be automaticallyfine tuned between the supporting arms 320 and the cover 31 of thesealing plug 3 of the present invention, so that the soft plate body 310of the cover 31 could be completely covered on the drain opening 421 ofthe overflow pipe 42, to thereby extend service life of the sealing plug3 to prevent water leakage problem, and the disadvantages of the priorart would effectively solved.
